OLga [1]

Answer:

3- is the charge and 8 dots on its Lewis dot structure.

Explanation:

Hello there!

In this case, since nitrogen is an element with five valence electrons (electrons on its outer shell), we infer that it needs three bonds to complete the octet, for which its charge, when forming nitride ions is 3-, which means it has received three electrons. Thus, when drawing the Lewis dot structure, it is evident that is will have 5+3 = 8 dots due to the electron reception.

GREYUIT [131]

The pH indicators to be used are Phenolphthalein, Red cabbage, Bromthymol blue and Congo red.

<h3>What are pH indicators?</h3>

Indicators are substances which change color as the pH of a medium changes.

The common indicators and their pH range is as follows:

Phenolphthalein - pH range of 8.3 and 10.5
Red cabbage - pH 2 to 10
Bromthymol blue - 6.0 to 7.6
Congo red - 3.0 to 5.2

Therefore, the indicators to be used are Phenolphthalein, Red cabbage, Bromthymol blue and Congo red.

A container holds a sample of hydrogen gas at 300 K. The temperature decreased to 100 K and the pressure remained constant, and

Charra [1.4K]

Answer : The original volume of gas was, 3.0 L

Explanation :

Charles' Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$

or,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=?\\T_1=300K\\V_2=1.0L\\T_2=100K$

Now put all the given values in above equation, we get:

$\frac{V_1}{300K}=\frac{1.0L}{100K}\\\\V_1=3.0L$

Thus, the original volume of gas was, 3.0 L

The mass of salt dissolved in 1.0 L of 0.010 M SO₄²⁻ is 0.67 g/l

<h3>How can we Calculate the mass of the salt dissolve in 1.0 L of 0.010 M SO₄²⁻ ?</h3>

To calculate the mass of the salt dissolved, we multiply by the mass of 1 mole to molar solubilty and lets assume we are using the anhydrous salt CaSO₄ for which the Molar Mass (M) = 136.1

Mass of the salt dissolved = Molar solubility x Molar mass

Molar Mass (M) = 136.1

Molar solubility = ?

Formula to find molar solubilty ;

Molar solubility = Square root of Solubity product (Given)

S = $\sqrt{2.4 x 10^{-5} }$ (Value of Solubity product is given in the question)

= 4.9 × 10⁻³

Mass of the salt dissolved = Molar solubility x Molar mass

= 4.9 × 10⁻³ x 136.1

= 0.67 g/l
